Selling on of my favourite custom mechanical keyboards Monsgeek M1.
Akko linear switches , all lubed, custom gaskets and dampening - all the fuss :)
It has backlight and volume knob. It is carved out of single block of aluminium and it sounds GREAT - I did a little sound test here : https://www.youtube.com/shorts/Rq1H7Qh74PM
Selling it only because I switched to split keyboards, and no longer can type on normal keyboard with a decent typing speed.
I can include some spare gaskets, and tools.
